World Lung Cancer Day: Early detection is key to tackling the silent killer, say experts
Recently, a 48-year-old male with a history of smoking experienced back pain and difficulty walking. He initially visited a physician who prescribed painkillers, but the discomfort persisted. Later, he consulted a neurologist who advised an MRI of the spine. The scan revealed signs of cancer, and a follow-up chest X-ray confirmed that the primary issue was in the lungs. The lung cancer had spread to his spine, causing spinal compression. Asserting that this case underlines how lung cancer often goes unnoticed until it has significantly progressed, Sachin Kumar, director, pulmonology and critical care medicine, Sakra World Hospital, where his cancer was diagnosed, said it is crucial to raise awareness that the disease may not always begin with clear symptoms. 'Timely health screenings can make a major difference,' he said. To raise awareness about lung cancer, its impact, and the importance of early detection and prevention, World Lung Cancer Day is observed annually on August 1. Risk factors 'While smoking and exposure to secondhand smoke are major risk factors, cases are now emerging in non-smokers as well. Factors such as genetics and environmental triggers may also play a role in deteriorating lung health,' the doctor said. Urging people to take proactive steps in protecting their lung health, doctors asserted that early detection can save lives in the fight against this often silent disease. Echoing the concern, Sunil Kumar K., lead consultant, interventional pulmonology, Aster CMI Hospital, said the biggest challenge of lung cancer is late diagnosis. 'Symptoms such as mild cough, breathlessness, or chest pain are often ignored or mistaken for other common conditions. By the time patients come to us, the disease is already in advanced stages,' he said. 'With early-stage detection, patients may avoid chemotherapy or radiation altogether, instead benefiting from surgery or targeted therapies'Dr. Sunil KumarPulmonologist Highlighting recent advances in technology, Dr. Sunil Kumar emphasised that low-dose CT scans can now detect small tumours early, improving the chances of curative treatment. 'With early-stage detection, patients may avoid chemotherapy or radiation altogether, instead benefiting from surgery or targeted therapies,' he said. Both doctors strongly advocated regular health checks, especially for high-risk individuals such as smokers and those exposed to industrial fumes, firewood smoke, or heavy pollution. Symptoms such as unexplained weight loss, chronic cough, or blood in sputum should not be ignored. Incidence In Karnataka, the incidence of cancer is increasing by about 1% each year in both men and women. Nearly 6% of around 88,000 cancer cases recorded in Karnataka every year are lung cancers. According to data from the State-run Kidwai Memorial Institute of Oncology, the institute sees around 25,000 new cancer cases every year. In 2024, about 21,051 new cases were registered, and over 3.89 lakh cancer patients had visited the institute for follow-up. Of the new cases, over 6% were diagnosed as lung cancers. 'Awareness and timely medical attention can turn this silent killer into a treatable condition,' the doctors said, adding that a simple scan at the right time can save a life.

Police: In 2022, Abhishek impersonated his brother
Police said Abhishek Kumar (then 22) had cleared the CISF constable recruitment exam in Noida on May 18, 2022 while posing as his younger brother Sachin Kumar. Later, out on bail, he sat for UP police constable direct recruitment exam in 2024 under his own name. But his past caught up. DSP (Etah) Gyanendra Pratap Singh said, "The omission came to light during a routine police verification, which usually takes place ahead of training. Abhishek was re-arrested in Etah Wednesday evening. Further investigations are on." SHO (Awagarh) Avdesh Kumar Dixit added, "Abhishek belongs to Katelia under Awagarh thana in Etah. In 2022, he impersonated his younger brother as he was overage for the CISF exam." An FIR was initially registered against 'Sachin Kumar' at Noida's Ecotech-III police station under IPC Sections 419 (cheating by personation), 420 (cheating and dishonesty), 467 (forgery) and 471 (using a forged document as genuine) after a complaint by CISF commandant Naresh Joshi, who was overseeing the recruitment process in 2022. After his arrest, Abhishek was remanded in custody as 'Sachin'. A chargesheet was filed on July 23, 2022 and the case remains pending in a Noida court. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 中年以降であれば、このゲームは必須です。 BuzzDaily Winners ゲームをプレイ Undo In 2024, Abhishek tried his luck again and appeared for UP police exam.

IIT Guwahati harnesses clay sedimentation to identify and measure Coronavirus
Guwahati: Indian Institute of Technology Guwahati researchers have developed a novel method for detecting and measuring the amount of SARS-CoV-2, the virus that causes COVID-19. The innovative approach is based on how quickly a clay-virus-electrolyte mixture settles; a process commonly known as sedimentation, offering a simple and affordable alternative to the complex and expensive methods currently in use for virus detection. The findings of this research have been published in the prestigious peer-reviewed journal, Applied Clay Science, in a paper co-authored by Prof. T V Bharat, Department of Civil Engineering, and Prof. Sachin Kumar, Department of Biosciences and Bioengineering, along with research scholars Dr Himanshu Yadav and Deepa Mehta at IIT Guwahati . Posing a threat to human lives globally, COVID-19 pandemic revealed a critical gap in how viral infections are detected and tracked. Current methods, such as Polymerase Chain Reaction (PCR), are highly sensitive but time-consuming and require heavy equipment. Similarly, the antigen testing is fast but lacks accuracy, while antibody testing is used after the infection has occurred, highlighting limitations at various levels. Additionally, many of these methods are not practical in resource-limited settings or during large-scale outbreaks. To address these gaps, Prof. T V Bharat, Dept. of Civil Engineering, IIT Guwahati, along with his research team has used Bentonite clay, a clay well known for its ability to absorb pollutants and heavy metals due to its unique chemical structure in collaboration with Prof. Sachin Kumar, Department of Biosciences and Bioengineering. Previous studies have shown that clay particles can bind with viruses and bacteriophages, making it a promising material for virus detection. The research team focused on how Bentonite clay interacts with virus particles in a salt environment. The research team found that a Coronavirus surrogate and Infectious Bronchitis Virus (IBV) bind to the negatively charged clay surfaces at a controlled room temperature and a neutral pH of 7. Speaking about the findings of the research, Prof. T V Bharat said, "Imagine a world where detecting viruses is as simple as watching sand settle in water. That is the breakthrough we have achieved! Our new method uses clay to quickly identify and measure viruses, like the coronavirus. By observing how the clay settles in a solution, we can determine if a virus is present and how much of it there is. This innovative approach offers a faster, more affordable, and accurate alternative to current methods, paving the way for better disease monitoring and treatment strategies, especially during pandemics, this study is in continuation with our recent studies published in prestigious journals like Langmuir in developing exclusive biomedical waste facilities for disposing pathogenic waste sponsored by Department of Science and Technology, Government of India." The research team validated their findings using established virus-detection methods, including plaque assay for a coronavirus surrogate and RT-PCR for IBV. The developed technique produced accurate results in comparison to the standard detection methods, reinforcing its reliability. Notably, the method can be extended to detect other viruses such as the Newcastle Disease Virus (NDV), which affects poultry and causes major losses in the farming industry. This development holds great promise for improving how viral outbreaks are monitored and controlled, especially in regions where expensive lab equipment and trained personnel are not readily available. With further refinement, the method could be adapted for use in field kits or simple laboratory setups, making virus detection more accessible and efficient in future public health emergencies. As the next step, the research team is planning to collaborate with industry partners with medical facilities for clinical trials for SARS-Cov-2 and other viruses. By partnering with industry, the research team hopes to leverage the resources and expertise necessary to conduct robust clinical trials and ultimately contribute to the global effort to combat viral infections.

IIT Guwahati develops low-cost way to measure COVID-19 using clay
A research team at IIT Guwahati has come up with a new way to detect the virus that causes COVID-19 -- using clay and salt water. This method doesn't rely on heavy lab equipment or complex tests. Instead, it watches how a mix of clay, virus, and salt water settles over time, a process known as study, led by Professor TV Bharat from the Department of Civil Engineering and Professor Sachin Kumar from the Department of Biosciences and Bioengineering, explores the use of Bentonite for sticking to pollutants, this clay also binds with viruses when placed in the right environment -- room temperature and a neutral pH.'Think of it like watching mud settle in a glass of water,' Prof. Bharat explained. 'The way the clay falls can tell us if a virus is there and how much of it is present.'The team tested the method using a virus similar to coronavirus and the Infectious Bronchitis Virus (IBV). They checked the results using existing detection tools like RT-PCR and plaque assays. The clay-based approach gave matching results -- without the need for expensive method could be useful not just for detecting COVID-19 but also other viruses, like those affecting poultry farms. It could be especially handy in places that don't have access to high-end researchers now plan to team up with medical labs and industry players to test this approach on real-world samples. If all goes well, they hope to turn it into a simple field kit for future idea -- watching how fast clay sinks -- could become part of how we deal with virus outbreaks in the future, especially in areas that need quick, low-cost solutions. advertisement

25yo Delhi man swept away while bathing in Ganga at Rishikesh
Haridwar: A 25-year-old man from Delhi was swept away while bathing in the Ganga at the Golf Course ghat in Rishikesh on Thursday afternoon. The deceased, identified as Sachin Kumar, was a resident of Nirman Vihar in Delhi and had arrived in Haridwar earlier in the day with a female companion. Officials said that Sachin ventured into deep waters and was swept away by the strong current while his friend remained on the riverbank. "Our teams launched a search operation immediately, but we've not been able to trace him so far," said State Disaster Response Force (SDRF) area in-charge Kavindra Sajwan. He added that Sachin was employed at a private firm in Delhi and his family has been informed about the incident. Search and rescue operations by the SDRF were on till the filing of this report. The incident adds to a growing list of drowning cases in the region. On Sunday, Guddu Yadav, a supervisor at a Gurgaon-based transport company, drowned in Rishikesh. Just last month, Pradeep Dhaka, a 35-year-old bank employee from Haryana, drowned in the Chilla canal. In another incident, the bodies of two young girls swept away by the Ganga were recovered by SDRF in April. "Till Jan, we recovered around 20 bodies from the river—most of them from the Rishikesh region—while eight persons were rescued by our teams from the Rishikesh and Raiwala areas," said Sajwan.
